Durch Behandlung von Borsäure mit Alkali oder durch Behandeln von Borax mit Borsäure in wäßriger Lösung hat man bisher nur Borax, metaborsaures Natron, und ein Salz der FormelBy treating boric acid with alkali or by treating borax with boric acid Up to now, only borax, sodium bicarbonate and a salt have been found in aqueous solution the formula
NaBO2 + 4HBO2 + 3V2 H2O NaBO 2 + 4HBO 2 + 3V 2 H 2 O
in fester Form abscheiden können. Das letztere Salz erhielt Laurent, als er ein Äquivalent Borax mit drei Äquivalenten Borsäure in Reaktion brachte Arbeitet man dagegen so, daß auf ein Äquivalent Borax vier Äquivalente Borsäure zur Einwirkung gelangen, so erhält man ein ganz anderes Resultat. Es bildet sich bei Einhaltung bestimmter Konzentrationen eine neue Verbindung der Formelcan deposit in solid form. The latter salt was given to Laurent when he was an equivalent Brought borax into reaction with three equivalents of boric acid. that for one equivalent of borax four equivalents of boric acid come into play, so you get a completely different result. It is formed when certain concentrations are adhered to a new compound of the formula
NaHBt07+ 41ZiH9O,NaHB t 0 7 + 4 1 ZiH 9 O,
die direkt auskristallisiert und ihrer Zusammensetzung nach das saure Natronsalz der Tetraborsäure darstellt. Das Salz ist eine leichtlösliche einheitliche Verbindung, die sich aus Wasser unverändert kristallisieren läßt und eine konstante Zusammensetzung aufweist. Man kann dasselbe Salz auch aus freier Borsäure gewinnen, indem man auf diese eine entsprechende Menge Alkali (oder ein geeignetes Alkalisalz) einwirken läßt.which crystallizes out directly and its composition after represents the acidic sodium salt of tetraboric acid. The salt is an easily soluble uniform compound that is Can crystallize unchanged from water and has a constant composition. The same salt can also be obtained from free boric acid by adding one Allow the appropriate amount of alkali (or a suitable alkali salt) to act.
Analyse: 1 g Salz verbrauchte bei der Titration 7,6 ecm Y2 η Salzsäure und 30,8 ecm V2 η Kalilauge. 1 g Salz verlor beim Erwärmen auf 1400 bis zur Gewichtskonstanz 0,3116 g H2O. Aus diesen Zahlen ergibt sich das Verhältnis von Alkali zu Säure 1 zu 4 und die FormelAnalysis: 1 g of salt consumed 7.6 ecm Y 2 η hydrochloric acid and 30.8 ecm V 2 η potassium hydroxide solution in the titration. 1 g of salt lost on heating to 140 0 to constant weight 0.3116 g H 2 O. From these figures results in the ratio of alkali to acid is 1 to 4 and the formula
NaHB^1 + 41Z2H2O NaHB ^ 1 + 4 1 Z 2 H 2 O
für das kristallisierte Salz.for the crystallized salt.
Das Salz unterscheidet sich vom Borax scharf; es zeigt mit Phenolphtalein keine Rötung, liefert mit Silbernitrat einen weißen Niederschlag, der sich beim Kochen nicht bräunt, zeigt eine Löslichkeit in Wasser, welche diejenige des Borax und die der Borsäure um das 15- bis 25fache übertrifft. Es bildet ein weißes, nicht hygroskopisches Kristallpulver von schwach saurem Geschmack. Es lassen sich mittels dieses Salzes Lösungen in Wasser herstellen, die syrupös sind und die desinfizierenden Eigenschaften der Borsäure in hohem Maße zeigen, so daß das Salz als Ersatz der freien Borsäure benutzt werden kann. Das Salz unterscheidet sich durch seine Eigenschaften, namentlich seine große Löslichkeit, auch scharf von einem in der Literatur beschriebenen SalzThe salt differs sharply from the borax; it shows no reddening with phenolphthalein, with silver nitrate provides a white precipitate that does not appear when cooked browns, shows a solubility in water which is that of borax and that of boric acid exceeds 15 to 25 times. It forms a white, non-hygroscopic crystal powder slightly sour taste. This salt can be used to create solutions in water that are syrupy and have high disinfectant properties of boric acid Dimensions show that the salt can be used as a substitute for free boric acid. That Salt differs in its properties, in particular its high solubility, also sharp from a salt described in the literature
Na2O- 4B2O3-10F2O, Na 2 O- 4B 2 O 3 - 10F 2 O,
welches dieselbe Summenformel hat und durch Kochen von Borax mit Salmiaklösung erhalten worden ist. Es löst sich in 5 bis 6 Teilen kalten Wassers. Nach Atterberg ist dieses Salz eine Mischung zweier Salze der Formelwhich has the same molecular formula and obtained by boiling borax with ammonia solution has been. It dissolves in 5 to 6 parts of cold water. According to Atterberg, this is Salt a mixture of two salts of the formula
